You know, as far as the boxwood stuff goes . . . it might be helpful for you to try to use something like NasalCrom, which is available at places like Walgreen’s over-the-counter. It has almost zero side effects (it does smell funny), but it can help stabilize the immune cells in your nose not to react with congestion to a little boxwood dust.
Ah, if only you’d suggested that before 2 days ago…
I spent the entire day yesterday sorting though boxes and crates of, well, boxwood, for the purpose of sizing and culling our stock, and I’m still suffering a bit today. Actually though, since next week I’ll be band sawing, gun drilling, and turning quite a bit, I may think about taking your suggestion, since wearing the mask doesn’t prevent me from getting covered in dust, and the mask has to come off for meals, repairs, etc.
I have a couple of the helmet type masks which blow filtered air over the face from a belt mounted pack .Without them the dust from working pernambuco wood in making violin bows would soon finish me off ( much to the delight , no doubt, of Mr L Migoya ! ).They are a bore to use, though.
IgE strikes again ! It was the IgD got me !
3 years ago I purchased a Cocuswood Prattens Perfected (made in ~1860) from a guy who was unable to play it due to an allergic reaction which affected his mouth and lips almost as soon as he touched it.
I played that flute daily for two years without any problems, including long sessions and occasional performances - and though I am now more often playing a 6 key McGee Rudall and Rose model, it is not as a result of any difficulty with the Prattens.
It seems that whatever causes the allergy stays around in the timber for a very long time. I understood that Cocus was a relative of poison ivy, and that the poison and the human reaction is similar. I have no scientific knowledge on that, its just something I heard somewhere.
Some of us are very lucky to be free of such problems.
